Zucchini is a summer squash. Summer squashes are members of the gourd family, cousins of winter squash. They come in a variety of sizes, shapes, and colors. Zucchini, yellow crookneck, and pattypan (scallop) squash are common varieties of summer squash. Zucchini is also called marrow (vegetable marrow or Italian marrow) and courgette, depending on where in the world you live.
Zucchini is easy to find in most markets and provides micronutrients, such as vitamins C and B6. This versatile vegetable (that is technically a fruit) is low in calories and makes a great addition to most healthy diets.
